The Demon, Etrigan (DC Universe)
Originally summoned from the pits of hell by the wizard Merlin to defend Camelot from the witch, Morgana Le Fey, Etrigan in recent years has become a monster possessed by the soul of his human host Jason Blood. He can transform between his demon and human forms only if a special incantation is read. Although adept at magic and sorcery, The Demon, Etrigan prefers to blast his opponents to cinders with his fire breath.
Includes the "left arm" of Rex Mason The Element Man.
